Rule 15. Depositions
(a) When Taken.
(1) In General. A party may move that a prospective witness be deposed in order to preserve testimony for trial. The court may grant the motion because of exceptional circumstances and in the interest of justice. If the court orders the deposition to be taken, it may also require the deponent to produce at the deposition any designated material that is not privileged, including any book, paper, document, record, recording, or data.
(2) Detained Material Witness. A witness who is detained under 18 U.S.C. § 3144 may request to be deposed by filing a written motion and giving notice to the parties. The court may then order that the deposition be taken and may discharge the witness after the witness has signed under oath the deposition transcript.
(1) In General. A party seeking to take a deposition must give every other party reasonable written notice of the deposition’s date and location. The notice must state the name and address of each deponent. If requested by a party receiving the notice, the court may, for good cause, change the deposition’s date or location.
(c) Defendant’s Presence.
(1) Defendant in Custody. The officer who has custody of the defendant must produce the defendant at the deposition and keep the defendant in the witness’s presence during the examination, unless the defendant:
(2) Defendant Not in Custody. A defendant who is not in custody has the right upon request to be present at the deposition, subject to any conditions imposed by the court. If the government tenders the defendant’s expenses as provided in Rule 15 (d) but the defendant still fails to appear, the defendant—absent good cause—waives both the right to appear and any objection to the taking and use of the deposition based on that right.
(d) Expenses. If the deposition was requested by the government, the court may—or if the defendant is unable to bear the deposition expenses, the court must—order the government to pay:
(1) any reasonable travel and subsistence expenses of the defendant and the defendant’s attorney to attend the deposition; and
(e) Manner of Taking. Unless these rules or a court order provides otherwise, a deposition must be taken and filed in the same manner as a deposition in a civil action, except that:
(2) The scope and manner of the deposition examination and cross-examination must be the same as would be allowed during trial.
(f) Use as Evidence. A party may use all or part of a deposition as provided by the Federal Rules of Evidence.
(g) Objections. A party objecting to deposition testimony or evidence must state the grounds for the objection during the deposition.
